A hollow body includes a wall which at least partially surrounds an interior volume of the hollow body. The wall comprises a layer of glass and has a wall surface. The wall surface comprises a surface region which is characterized by a contact angle for wetting with water of at least 80°. A process for making an item; a hollow body obtainable by this process; a closed container; a process for packaging a pharmaceutical composition; a closed hollow body obtainable by this process; a use of one of the hollow bodies; and a use of a perfluorinated silane or a perfluorosulfonic acid or both is also provided.

Hollow body, in particular for packaging a pharmaceutical composition, having a layer of glass and a surface region with a contact angle for wetting with water

A liquid preparation for application to an inner side of a hollow body to produce a sliding layer on a packaging for pharmaceuticals or cosmetic products comprises the following constituents: a reactive silicone system for forming a silicone network of the sliding layer, a catalyst for catalyzing the cross-linking reaction of the reactive silicone system, at least one unreactive silicone oil, and at least one diluent. The diluent comprises a silicon-containing compound and a content of the at least one diluent in the preparation amounts to more than 45 percent by weight and less than 95 percent by weight in the preparation.

A hollow body includes a wall which at least partially surrounds an interior volume of the hollow body. The wall comprises a layer of glass comprising a first glass composition, comprises a base surface, and has a wall surface. The wall surface comprises at least one surface region, in which the base surface is at least partially superimposed by at least one elevated region, and at least one contact region, which extends along a contact range of a height of the hollow body. The at least one elevated region comprises a further glass composition. An exterior diameter of the hollow body has a maximum throughout the contact range. The at least one surface region is at least partially positioned in the at least one contact region.

A method for producing a glass or glass ceramic composite material with a metallic decorative appearance is provided. The method includes: applying a layer onto a glass or glass ceramic substrate, the layer comprising a sol-gel and/or a polysiloxane; patterning the layer; and applying a metallic-looking layer onto the patterned layer.

A leached fiber bundle with the light outlet points positioned as accurately as possible is provided, in which the end faces are not completely fused together, but rather are only fused together at their contact surfaces. The interstices formed are permanently filled with adhesives with the aid of a pressure reduction. To protect the optical fibers from mechanical load, adhesives are introduced into the transition region between the fixed end region and a flexible region. This allows the leached fiber bundles to be produced more economically and also improves their service life.
